Computational Light Painting Using a Virtual Exposure
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Light painting is an artform where a light source is moved during a long-exposure shot, creating trails resembling a stroke on a canvas. It is very difficult to perform because the light source needs to be moved at the ...
Overview + Detail Visualization for Ensembles of Diffusion Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
A Diffusion Tensor Imaging (DTI) group study consists of a collection of volumetric diffusion tensor datasets (i.e., an ensemble) acquired from a group of subjects. The multivariate nature of the diffusion tensor imposes ...
Spectral Processing of Tangential Vector Fields
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
We propose a framework for the spectral processing of tangential vector fields on surfaces. The basis is a Fourier‐type representation of tangential vector fields that associates frequencies with tangential vector fields. ...
